Standoff on Humboldt Hill

A man of interest in a Glendale, Ariz., homicide - who had been in a standoff with local law enforcement for about 12 hours at a Mesa Avenue home on Humboldt Hill - apparently shot and killed himself at around 9:30 a.m.

The unidentified man was not believed to have any hostages, and the SWAT team, crisis negotiators and county mental health officials were on the scene throughout the night.

Humboldt County Sheriff's deputies received a call from the Glendale Police Department at about 10 p.m. Wednesday informing them that GPD believed a person of interest in a homicide investigation may be in Humboldt County. Deputies then went to the home of the person of interest's mother and were able to confirm that the person was in the building, according to officials at the scene, who said the person's mother and a man receiving hospice care were also in the residence.

Law enforcement officers then surrounded the building, and asked the man to come out. The man refused to comply, but stayed in communication with officers at the scene throughout the night, according to officials.

Shortly before 11 p.m. Wednesday, officials said the man's mother safely left the residence, according to officials. Then, around 2:15 this morning, a rescue team went into the house and safely remove the man receiving hospice care, according to officials. At just after 10 a.m., it was released that the man had indeed shot himself.
